Abstract[English]
electrolysis in a zero-gap cell electrolyzer is suggested, comprising an anion exchange ionomer layer, wherein said anion exchange ionomer layer comprises microparticles and/or nanoparticles at a weight percent between 1 wt. % and 50 wt. %, wherein the microparticles and/or nanoparticles comprise or are formed of a metal oxide. According to the invention, the membrane assembly (10) furthermore comprises a catalyst layer (12) comprising a copper-based cathode catalyst, the anion exchange ionomer layer and the catalyst layer (12) together forming a membrane electrode assembly.[French]
dans un électrolyseur de cellules à espace nul est suggéré, comprenant une couche ionomère échangeuse d'anions, ladite couche ionomère échangeuse d'anions comprenant des microparticules et/ou des nanoparticules à un pourcentage en poids compris entre 1 % en poids et 50 % en poids, les microparticules et/ou les nanoparticules comprenant ou étant formées d'un oxyde métallique. Selon l'invention, l'assemblage membrane (10) comprend en outre une couche de catalyseur (12) comprenant un catalyseur de cathode à base de cuivre, la couche d'ionomère d'échange d'anions et la couche de catalyseur (12) formant ensemble un assemblage membrane-électrodes.
